" This I can firmly assert, that I have not written one word in the present work that 

 I cannot prove by authentic documents. Many of the facts I relate, I have myself been 

 the eye-witness of; aad of others, I possess manuscripts, written by men of information 

 and honour who have witnessed them. I have likewise consulted all that has been pub* 

 lished on the subject." Author'* Preface.
